Slide 4:
Decomposition reactions
DEFINATION:
DEFINATION A chemical reaction in which a single compound decomposes or splits up into two or more simpler substances is called decomposition reaction Example:
Types of decomposition reactions:
Types of decomposition reactions The decomposition reactions require energy in the form of HEAT, LIGHT OR ELECTRICITY.Hence,decompositon reactions are of three types Thermal decomposition Photolysis Electrolysis
Thermal decomposition:
Thermal decomposition I t is a decomposition brought about by heat Example: Water when heated over 2000c
PHOTOLYSIS:
PHOTOLYSIS It is a decomposition brought about by light Example:
ELECTROLYSIS:
ELECTROLYSIS It is a decomposition reaction brought about by electricity Example: at cathode at anode
